Hugh Hefner and his fiancée Crystal Harris welcome ET's Kevin Frazier into the Playboy Mansion for the dish on their wedding, their 60-year-age gap, and whether or not they plan on having kids!
Hugh and Crystal tell Kevin they're eyeing a summer wedding at the Mansion, an "intimate" ceremony with close friends and family -- "no big, blow-out affair," Hef says.
"Giving it another chance after a couple of failed marriages is an adventure, but it's something that I'm committed to," the Playboy mogul says.
But what about that big age gap between 84-year-old Hef and 24-year-old Crystal? Is it problematic? "I don't notice the age difference with Hef at all," Crystal says. "If anything I have to keep up with him."
Speaking of keeping up, Kevin's gotta wonder: Is Hugh still sexually active? "I'm doing my best. Dancin' as fast as I can," the energetic 80-something says with a smile.
Which begs the question: Does Hef want more children? "Well, we'll see. That's not part of the big plan," he says.
One thing that's not in question: Hef's love for his Playmate bride-to-be. "She's a beautiful human being inside and out; a woman with real character and humor," he says. "We're really devoted to each other. I think that the relationship is the center of both our lives."
